California’s coldest storm of the season continues, and it will deliver feet of Sierra snow and locally flooding rain, but also much-needed replenishment to a western snowpack that is record low for this time of year from the Pacific Northwest to the Southern Rockies. A powerful avalanche led to search and rescue crews looking for backcountry skiers on Tuesday around 11:30AM. This avalanche was caused by very high snowfall rates and gusty winds, which weakened the snowpack layer. Snowfall reports have already exceeded 3 feet at Soda Springs with more to come for the Sierra Nevada this week. An Avalanche Warning remains in effect. Interstate 80 remains closed in both directions over Donner Summit, due to whiteout conditions and winds gusting as high as 100 MPH.
